WILLOUGHBY MOFFAT, OF HAMILTON, ONTARIO, CANADA.

MOP-WBINGER Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed August 6, 1907. Serial No. 387,351.

To all whom it may concern:

Be it known that I, WILLOUGHBY MoFFAT, subject of the King of Great Britain, residing at Hamilton, in the district of Wentworth, Province of Ontario, Canada, have invented certain new and useful Improvements in Mop- Wringers, of which the following is a specification.

The present invention relates to certain new and useful improvements in mop wringers of that type which embody a pair of cooperating rollers designed to be mounted upon a suitable receptacle so as to grip a mopcloth between the same.

The object of the invention is to design a simple and inexpensive mop wringer of this character and the invention contemplates novel means for mounting the fixed roller and guiding the mop into contact with the same, and a novel treadle mechanism for operating the movable roller.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure l is a perspective view of a pail having the mop wringer applied thereto. Fig. 2 is a vertical sectional view through the same, the rollers being shown as moved into an operative position. Fig. 3 is a top plan view of the same. Fig. 4 is an enlarged detail view of one of the inner brackets upon which the fixed roller is journaled. Fig. 5 is a similar view of one of the outer brackets upon which the swinging frame is mounted. Fig. 6 is a sectional view through one of the outer brackets upon which the swinging frame is mounted.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The mop wringing device may be applied to any suitable receptacle such as the pail 1 which is of the conventional construction. The fixed roller 2 is arranged within the mouth of the receptacle 1 preferably slightly to one side of the same and is journaled upon the inner brackets 3 secured to the interior of the pail adjacent the upper edge thereof. Each of these inner brackets 3 comprises a body portion which is rigidly connected to the inner face of the pail by any suitable fastening means such as the bolts 4, and a laterally extending wing 5 which projects over the upper edge of the pail and is preferably located immediately over the opening 6 which serves as a bearing for the pin at the end of the roller 2. It will also be observed that an inwardly extending guide flange 7 is formed in conjunction with each of the inner brackets 3, the said guide flanges having their inner edges inclined and serving the double function of guiding a mop cloth into contact with the fixed roller and preventing the same from slipping around the ends of the roller and being wound upon the pivot ins thereof. Projecting upwardly from each of the inner brackets 3 is an integral ear 8, the said ears being slightly offset from the interior walls of the receptacle and serving as a means for securing a bail 9 of the usual construction thereto.

The movable roller 10 is somewhat greater in length than the width of the receptacle 1 and is journaled upon a foot actuated swinging frame. A spring normally holds the movable roller in the position shown in Figs. 1 and 3 in which a comparatively large space exists between the two rollers, the said space permitting the mop to be readily inserted within the pail or placed in position against the fixed roller for being wrung when the movable roller is brought into contact therewith. This swinging frame comprises the upright arms 11 carrying the movable roller 10 and the lateral arms 12 which are made rigid with the upright arms by any suitable means such as the braces 13 and are connected by an arched cross piece 14 carrying a foot piece 15. Outer brackets 16 are secured to the exterior of the receptacle 1 and are formed with stub shafts 17 upon which the swinging frame is mounted. Enlargements are located at the base of the stub shafts 17 and the said enlargements are surrounded by coil springs 18, one of the ends of each of the springs engaging a lug 19 upon the bracket while the opposite end is hooked as indicated at 20 and engages the upright arm 11 of the swinging frame. As has been previously mentioned these springs operate to hold the movable roller 10 spaced from the fixed roller so as to permit the mop to be readily inserted within the receptacle or laced in position against the fixed roller. n the present instance each of the outer brackets 16 is shown as formed upon its inner face with a groove 21 designed to receive one of the reinforcing bands extending around ary foot piece 23 is rigidly connected to the bottom of the pail upon one side thereof and is designed to extend outwardly over the floor or other support upon which the receptacle may be positioned.

In the operation of the wringer the mop cloth is placed against the fixed roller 2, the

guide flanges 7 serving to engage the sides of the mop cloth and to guide the mop into the proper position. The operator then places one of his feet upon the stationary foot piece 23 while with the opposite foot he presses downwardly upon the foot piece 15 until the movable roller 10 bears against the mop cloth with the required degree of pressure according to the dryness to which itis desired to wring the mop. An upward pull upon the mop then draws the mop cloth through the two rollers in such a manner as to wring the same. In this connection it is desired to call attention to the fact that the movable roller 10 bears against the upper portion of the fixed roller and this arrangement of the parts facilitates the wringing of the mop when pulling the same upwardly and also causes the pressure exerted by the movable roller against the fixed roller to aid in maintaining the receptacle in a steady position.

The inner brackets both serve to guide the mop into position against the fixed roller and to prevent the mop from passing aroundthe ends of the roller and winding about the spindle. The method of mounting the movable roller so that it engages with the upper surface of the fixed roller brings about a powerful downward pressure which is in a direct line with the foot piece, instead of a weak side pressure. The manner of mounting the rollers also facilitates the locating of the bail in the proper position to maintain the center of gravity and thus keep the pail level while being carried.

In securing the outer brackets 16 to the pail 1 either bolts or wood screws may be utilized although the latter are for many 7 reasons preferable since they do not extend entirely through the pail and there is less liability of leakage. As shown in the drawings three wood screws are employed, the middle screw being lowered below the end screws so as to be out of alinement therewith. Having thus describedthe invention, what is claimed as new is:

1. In a mop wringer, the combination of a receptacle, inner brackets applied to opposite sides of the receptacle, the said inner site sidesof the receptacle, the said brackets beingprovided at one end with wings designed to engage the edge of the receptacle and at the opposite end with lateral guide flanges, ears being provided which project upwardly from the brackets, said ears being designed to engage a bail, a fixed roller journaled between the brackets at points below the wings, a movable roller, and means for moving the movable roller into cooperative relation with the fixed roller.

3. In a mop wringer, the combination of a receptacle, inner brackets applied to the receptacle, each of said inner brackets being provided at one end with a wing designed to engage the edge of the receptacle, and at the opposite end with a lateral guide flange and also with means for engaging a bail, a fixed roller journaled between the brackets in cooperative relation to the guide flanges, a bail engaging the brackets, a movable roller, and

means for bringing the movable roller into cooperative relation with the fixed roller.

In testimony whereof I aflix my signature in presence of two witnesses.
